Cutting Tool Holder Flow Path and Recess Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cutting tool holders lack an efficient and integrated coolant supply mechanism that balances cooling effectiveness with structural strength and design flexibility, often compromising on one aspect for the other.
Innovation Solution
A cutting tool holder design featuring a flow path with strategically located outflow ports and recesses that allow for a coolant supply mechanism to be integrated within the holder, enhancing cooling efficiency while maintaining structural strength and design freedom, including a columnar shape with a quadrangular prism configuration and specific placement of outflow ports relative to recesses for optimal coolant flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a coolant supply mechanism is integrated into the holder, then cooling efficiency is improved, but structural strength deteriorates
Solution Approach 1:
The holder is divided into multiple portions (first portion, second portion, third portion) with the coolant supply mechanism integrated into specific regions. The outflow ports are strategically positioned in the first portion while maintaining structural integrity through the segmentation of functional zones within the holder body.
Solution Approach 2:
Different regions of the holder are assigned different functions: the first portion contains outflow ports for coolant delivery, the second portion provides structural support, and the third portion houses additional flow paths. This local differentiation allows optimal coolant distribution while preserving overall structural strength.
2Temperature
If outflow ports are positioned to optimize coolant flow, then cooling effectiveness is improved, but design flexibility deteriorates
Solution Approach 1:
The holder design incorporates multiple flow paths (first flow path, second flow path) that can serve different cutting insert configurations and cooling requirements. The outflow ports are positioned to provide universal coolant delivery capability across various cutting operations and insert types.
Solution Approach 2:
The coolant supply mechanism utilizes three-dimensional positioning of outflow ports within the holder structure, allowing coolant to be delivered from multiple directions and depths. This spatial arrangement provides design flexibility while maintaining optimal cooling effectiveness.
3Temperature
If recesses are added to the holder structure, then coolant distribution is improved, but manufacturing complexity increases
Solution Approach 1:
The recesses are integrated into the holder body as inherent structural features rather than separate components. The first recess and second recess are formed as part of the holder's core structure, combining coolant distribution functionality with the structural framework in a single manufacturing process.

AI summary
A cutting tool holder may include an upper surface; a first side surface; a second side surface adjacent to the first side surface; a pocket opening into the upper surface, the first side surface, and the second side surface; a first portion located lower than the pocket and protruded outward from the first side surface; and a flow path including an inflow port and an outflow port. The first side surface may include a first recess. The flow path may include a first outflow port opening into the first portion as the outflow port and a first flow path extending from the first outflow port into the holder. The first outflow port is located at a region of the first portion corresponding to the first recess.
